Abstract

With the content of ZnO varing from 10.5 to 47.4 wt%, the crystallization of lithium zinc silicate glass was investigated by DTA, XRD, and SEM. In this work P2O5 was used as nucleation agent. The crystallization temperature was found to increase with the content of ZnO and the microstructure of formed crystalling phases was studied through the scanning electron microscopy. According to the XRD analysis, the crystal phases formed are summarized as follows. 1) The major phases are lithium orthosilicate, lithium disilicate and quartz at 10.5 wt% ZnO. 2) Lithium zinc silicate polymorphous and cristobalite occur in the composition varying 21.3 to 30.8 wt% ZnO. 3) At composition containing 47.4wt% ZnO some quantity of willemite is formed.
